HTGEEK i tried to elude to it in my post, it will be fine, just get some long bolts.i would recommend 2 2" (1/4 20) thread bolts, with 4 nuts, and 4 washers. Thats what i used to get the angle correct. It kind of depends on where you are going to put your center? are you going to have it on top of a 5' TV like me? or a stand like Jake? the geometry of the vp-180 appears to be the same as the 150, so if your 150 upside down, with the angle side down and it works, then you should be able to put the 180 in the same orientation as the 150 and be fine. however, with the 180 having the treaded holes, you can use some bolts, to get a "more exact" angle like i needed to do.

The first thing I threw at the V3s was Dire Straits "Brothers In Arms 20th Anniversary Edition Multi. Ch. SACD. Now I had the Oppo default to 2ch on SACDs but switched to the 5.1 ....Wow! Was all I could muster, it was so effin sweet sounding. Oh yeah, the Oppo now defaults to multi. channel. Be back in a few days I have some music to listen to!
